Moi le francais ca me va bien :) 

for non french reader the above sentence means : french is no problem for me

Works fine here on MCP750. Hopefully matt porter did a copy on a better
ftp site :)

Was unable to test it because I could not get in ... Could you copy the zImage
elsewhere so that I can test the RAVEN feature?

I'm in favor of that :)

Well I can help here. I add to modify several line in the Makefile because
the PATH /usr/src/linux was used at several places. While preloader is not the
official preboot code It could help to have a line like

LINUX_DIR=/usr/src/linux

and then replace any /usr/src/linux by $(LINUX_DIR)...

Things are a little bit worse for console.c that has an absolute PATH.

I would suggest to make something like 

console.c : defkeymap.c

defkeymap.c:
	ln -s $(LINUX_DIR)/drivers/char/defkeymap.c .

and to have only

#include <defkeymap.c> in console.c
 
NOTE : of course this is needed only while we have it in a separate directory
       as other Makefile variable can be used if compiled in the linux tree...
